Tiling- 2 Aug 2026
Vasile refurbished my small upstairs bathroom two months ago. He replaced the tiling, re-routed pipework and installed a new toilet, radiator and sheet vinyl flooring. Re-routing the pipework (which was Vasile's idea) has made the bathroom more aesthetically pleasing and roomy. All the work was carried out to an excellent standard. Vasile was punctual and polite, answering my questions and addressing my concerns with patience.

Extensions- 20 Feb 2020
Decent builders but with extremely poor communication skills. First the good points: 1. They are good at internal finishes 2. They create and use a Statement of Work (SOW) to track all costs of the project, so there were no major surprises in the project 3. They are friendly and hard workers - who arrive on time Gotbath UK Ltd used subcontractors to build us a 6 meter rear extension. Although they had an in-house architect, they did not know the law around boundaries which resulted in a conflict with our neighbours. After spending hundreds on hiring a boundary surveyor, the initial wall had to be re-built within our boundary. Gotbath did not take any responsibility for the wrong information they provided to us regarding boundaries and charged us for the rebuild. When discussing how to finish the inside of the extension, GotBath were extremely slow in ordering supplies and in general responding to us, so we took matters into our own hands and ordered materials ourselves which were removed from the SOW provided to us. At the end of the project, finishes took a long time and required constant chasing. Final gas, electrical and warranty documents took a long time to reach us and required a lot of chasing too. I have very little confidence that GotBath will honour the warranty document they have provided to us. It's a shame because I can see GotBath have a lot of potential as a builder. However, their lack of communication has really let them down.

Electrical- 30 Oct 2025
Since Steve and his team came on board, the progress on site has improved significantly. Their professionalism, efficiency, and strong work ethic have made a real difference. Steve provided a very fair and reasonable quote, and his approach to the job has been both proactive and solution-focused. Even though the work is still in progress, it’s clear that Steve’s expertise and leadership are helping to move things forward faster and more smoothly than before. His attention to detail and willingness to go the extra mile have been greatly appreciated. I’m very pleased with the results so far and have full confidence that the finished work will be of a high standard. I highly recommend Steve and his team for any electrical work, they’re reliable, skilled, and a pleasure to work with.

Spoke with Contempo and they stated they would be able to attend to do the job that evening as they would be in the area, they arrived at the time stated and carried out the works there and then as required and expected. Provided a demonstration of the fan working and also installed the cupboard door to the face of the extractor unit. Cleared up and charged the amount that was agreed. Great, reliable and professional service.
